Description

Technical Field

[0001] This invention relates to potato seed processing technology, specifically to a potato seed cutting and wood ash coating machine. Background Technology

[0002] The potato seed cutting and wood ash coating machine is an integrated agricultural machine specifically designed to address the pain points in the pre-planting seed potato treatment process. It automates the quantitative cutting of seed potatoes and simultaneously performs wood ash coating. By combining the cutting and coating processes, the machine quickly dries the cut surfaces of the seed potatoes immediately after cutting using the water-absorbing properties of wood ash, forming a protective layer that effectively prevents post-cutting rot and bacterial infection. It also replaces traditional manual seed dressing, significantly improving processing efficiency and operational safety. This machine is particularly suitable for potato planting cooperatives and large-scale farms for the rapid and standardized preparation of seed potatoes before planting.

[0003] Chinese invention patent CN119586385B discloses an integrated intelligent potato seed cutting and selection machine. This patent uses a feeding conveyor belt to transport potato seed potatoes from a surrounding plate to an aligning device. The aligning device uses the forward movement of a double-headed conical roller and a single-headed conical roller to align the potato seed potatoes so that they enter the cutting device for cutting. The cutting device is installed at the end of the aligning device. A sorting and positioning device uses a first guide plate to guide the cut seed potatoes into a visual recognition device, which can collect the bud information of the cut potatoes. The selection device can select unqualified cut potatoes.

[0004] However, traditional conical rollers primarily rely on the friction between the roller surface and the seed potatoes to drive their movement. When the seed potato surface is wet, covered with soil, or has a highly irregular shape, the friction will decrease significantly, leading to slippage and weak pushing. When conical rollers are arranged at the feeding end, irregular seed potatoes can easily get stuck together, forming "arches" that cause congestion. Seed potatoes whose center of gravity is not at the geometric center are prone to generating eccentric torques on the conical rollers, resulting in high randomness in their movement. Summary of the Invention

[0005] The purpose of this invention is to provide a potato seed tuber cutting and wood ash coating processing machine, which solves the problems of friction drive failure, jamming and blockage and loss of control caused by the irregular shape of seed tubers in traditional conical roller alignment devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0016] A rack that meshes with several gears.

[0017] Furthermore, the side of the first spiral blade facing the seed potato conveying direction forms a first pushing surface for pushing the seed potato when the drive shaft rotates. The end of the first spiral blade near the cutting gap is inclined away from the drive shaft to form a first guide surface for guiding the seed potato into the cutting gap. The side of the second spiral blade facing the seed potato conveying direction forms a second pushing surface for pushing the seed potato when the drive shaft rotates. The end of the second spiral blade near the cutting gap is inclined away from the drive shaft to form a second guide surface for guiding the seed potato into the cutting gap.

[0018] Furthermore, the first helical blade in the middle of the drive shaft is fixedly connected to the adjacent second helical blade to eliminate the gap between them.

[0019] Furthermore, the frame is provided with a pushing assembly, which includes:

[0020] Mounting bracket, which is fixedly connected to the frame;

[0021] The first pushing inclined plate is fixedly installed on the mounting frame and corresponds to the first spiral blade, and is set above the first spiral blade. The first pushing inclined plate is inclined towards the cutting gap along the seed potato conveying direction.

[0022] The second pushing inclined plate is fixedly installed on the mounting frame and corresponds to the second spiral blade, and is set above the second spiral blade. The second pushing inclined plate is inclined towards the cutting gap along the seed potato conveying direction.

[0023] Several partition soft bristles are fixedly installed on the mounting frame and are arranged on the rear side of several first pusher inclined plates and several second pusher inclined plates along the seed potato conveying direction.

[0024] Furthermore, the alignment device also includes a receiving device, which comprises:

[0025] It receives the motor and is fixedly connected to the frame;

[0026] Both wheels are rotatably connected to the frame;

[0027] The conveyor belt is driven by two rollers and is located below a number of first helical blades and a number of second helical blades.

[0028] Furthermore, the dicing device includes:

[0029] The cutting motor is fixedly connected to the frame;

[0030] The cutting shaft is rotatably connected to the frame;

[0031] Several circular cutters are fixedly connected to the cutting shaft, and each corresponds to a certain cutting gap.

[0032] Furthermore, the coating device includes a coating assembly, the coating assembly comprising:

[0033] The receiving hopper is fixedly connected to the frame and is used to receive the seed potatoes after they have been cut into pieces.

[0034] The coating motor is fixedly connected to the frame;

[0035] Several drive wheels are rotatably connected to the frame, and all of them are connected to the output end of the coating motor.

[0036] Several support wheels are rotatably connected to the frame;

[0037] The coating roller has a bottom side connected to several drive wheels and a bottom side connected to several support wheels.

[0038] Several stirring paddles are fixedly connected to the middle of the inner wall of the coating drum;

[0039] Several reverse discharge devices are fixedly connected to the conical surface of the discharge end of the coating roller.

[0043] The nozzle is fixedly connected to and communicates with the delivery pipeline, and is located inside the coating roller;

[0044] An air pump is fixedly connected to the receiving hopper and is connected to the nozzle through an air pipe.

[0045] Compared with existing technologies, the present invention provides a potato seed potato cutting and wood ash coating processing machine. The seed potatoes are fed into the aligning device through a feeding device. The bidirectional pushing section in the middle uses the first and second spiral blades with opposite rotation directions to force the piled seed potatoes to turn over and tear, actively breaking up the congestion. The unidirectional pushing section at the edge sorts the seed potatoes with a single-direction pushing force. The first guide surface, the second guide surface and the upper pushing inclined plate work together to guide the seed potatoes when they reach the edge of the cutting gap. At the same time, the soft bristles on the rear side prevent the seed potatoes from rolling and interfering. This whole set of actions solves the problem of friction drive failure and jamming caused by the irregular shape of seed potatoes in traditional conical rollers, ensuring that the seed potatoes enter the cutting position continuously and accurately, providing a stable guarantee for subsequent cutting.

[0046] The circular cutters in the cutting device, each corresponding to a specific cutting gap, rotate at high speed under the drive of a motor, neatly cutting the seed potatoes and achieving linkage between the cutters and the arranging device. At the same time, smaller seed potatoes that do not need to be cut fall directly from the cutting gap during the arranging process and are automatically sorted and transported to the next process by the receiving device below. This avoids waste and equipment jamming caused by small seed potatoes entering the cutting process, and achieves automatic grading, which not only improves the utilization rate of raw materials, but also ensures the continuity and accuracy of the cutting operation.

[0061] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0062] Please see Figures 1 to 11 A potato seed tuber cutting and wood ash coating processing machine includes a frame 1, wherein the frame 1 is fixedly connected in sequence along the seed tuber conveying direction with:

[0063] Feeding device 2 is used to store and transport seed potatoes;

[0064] The alignment device 3 includes a drive assembly 31, a plurality of drive shafts 32, a plurality of first helical blades 33 and a plurality of second helical blades 34. The first helical blades 33 located in the middle of the drive shaft 32 are symmetrically arranged with the adjacent second helical blades 34, and the two are synchronously fixedly connected to the drive shaft 32 in a ring array to form a bidirectional pushing section. The first helical blades 33 and the second helical blades 34 located at both ends of the drive shaft 32 constitute a unidirectional pushing section. A cutting gap 35 is formed between two adjacent bidirectional pushing sections and between the bidirectional pushing section and the adjacent unidirectional pushing section.

[0065] Cutting device 4 is used to cut the arranged seed potatoes into pieces;

[0066] Feeding channel 5 is used to receive seed potatoes after they have been cut into pieces;

[0067] The coating device 6 is used to coat the cut seed potatoes with wood ash.

[0068] During operation, the feeding device 2 stably conveys the seed potatoes to the aligning device 3. The aligning device 3 drives the drive shaft 32 to rotate via the drive assembly 31, causing the first spiral blade 33 and the second spiral blade 34, which are fixedly connected to the shaft, to rotate synchronously with the shaft. In the bidirectional pushing section, since the symmetrically arranged blades rotate in opposite directions, they generate axial thrust in opposite directions during rotation, which forces the piled-up or stuck seed potatoes to turn over and tear, forcing most of the seed potatoes to automatically change their posture to break the congestion and move to the cutting gap 35 between two adjacent bidirectional pushing sections. The remaining seed potatoes located at the edge of the drive shaft 32 are initially sorted and then enter the unidirectional pushing section and the adjacent bidirectional pushing section. Between the pushing sections, because the blades rotate in the same direction, the rotation generates a stable thrust in one direction, which pushes the seed potatoes to the cutting gap 35 between the unidirectional pushing section and the adjacent bidirectional pushing section. The seed potatoes at the cutting gap 35 are precisely cut into pieces by the cutting device 4. After being cut, the seed potatoes fall into the coating device 6 through the feeding channel 5, where they are thoroughly mixed with wood ash. The water absorption properties of the wood ash are used to quickly dry the cut surfaces and form a protective layer, thus efficiently and integratedly completing the integrated operation from seed potato sorting and cutting to coating and disease prevention. This solves the problem that the traditional conical roller aligning device 3 is prone to friction drive failure, jamming, and loss of control due to the irregular shape of the seed potatoes.

[0069] Driver component 31 includes:

[0070] The drive motor 311 is fixedly connected to the frame 1;

[0071] A plurality of gears 312 are fixedly connected to a plurality of drive shafts 32, and one of them is fixedly connected to the output end of a drive motor 311;

[0072] A rack 313 meshes with several gears 312.

[0073] During operation, the drive motor 311 starts, driving a gear 312 to rotate. The gear 312 meshes with the rack 313, converting the rotational motion into the linear motion of the rack 313. Since the rack 313 meshes with the gears 312 on all other drive shafts 32 at the same time, the linear movement of the rack 313 drives all gears 312 to rotate synchronously, thereby driving all drive shafts 32 to rotate synchronously. This design ensures synchronous operation between the drive shafts 32, avoids seed potato conveying disorder caused by speed differences, and provides a stable and reliable power foundation for the subsequent precise sorting of seed potatoes by the alignment device 3.

[0074] The side of the first spiral blade 33 facing the seed potato conveying direction forms a first pushing surface 331 for pushing seed potatoes when the drive shaft 32 rotates. The end of the first spiral blade 33 near the cutting gap 35 is inclined away from the drive shaft 32 to form a first guide surface 332 for guiding seed potatoes into the cutting gap 35. The side of the second spiral blade 34 facing the seed potato conveying direction forms a second pushing surface 341 for pushing seed potatoes when the drive shaft 32 rotates. The end of the second spiral blade 34 near the cutting gap 35 is inclined away from the drive shaft 32 to form a second guide surface 342 for guiding seed potatoes into the cutting gap 35.

[0075] During operation, the drive shaft 32 rotates, causing the first spiral blade 33 and the second spiral blade 34 to rotate synchronously. The first spiral blade 33 and the second spiral blade 34 exert an axial thrust on the seed potato on the side facing the conveying direction, causing it to move towards the cutting gap 35 during the pushing process. When the seed potato reaches the edge of the cutting gap 35, the first guide surface 332 and the second guide surface 342 formed by the blade end near the gap tilting away from the drive shaft 32 correct the movement trajectory of the seed potato and guide it smoothly into the cutting gap 35. This dual structure design of "push surface advancement and guide surface introduction" ensures that the seed potato can smoothly and accurately enter the cutting position, improving the accuracy and continuity of the cutting operation.

[0076] The first helical blade 33 in the middle of the drive shaft 32 is fixedly connected to the adjacent second helical blade 34 to eliminate the gap between them.

[0077] During operation, the first helical blade 33 located in the middle of the drive shaft 32 is fixedly connected to the adjacent second helical blade 34, combining the two originally independent blade segments into a single structure and eliminating any potential gaps between them. This design serves two purposes: firstly, it eliminates the risk of seed potatoes getting stuck in the gaps at the blade connection points during operation; secondly, it eliminates blind spots in the pushing force caused by gaps, ensuring that the seed potatoes receive continuous and smooth force during the bidirectional pushing section, thereby further improving the smoothness and reliability of the alignment device 3.

[0078] The frame 1 is provided with a pusher assembly 36, which includes:

[0079] Mounting bracket 361 is fixedly connected to frame 1;

[0080] The first pushing inclined plate 362 is fixedly installed on the mounting frame 361 and corresponds to the first spiral blade 33, and is set above the first spiral blade 33. The first pushing inclined plate 362 is inclined towards the cutting gap 35 along the seed potato conveying direction.

[0081] The second pushing inclined plate 363 is fixedly installed on the mounting frame 361 and corresponds to the second spiral blade 34, and is set above the second spiral blade 34. The second pushing inclined plate 363 is inclined towards the cutting gap 35 along the seed potato conveying direction.

[0082] Several partition soft bristles 364 are fixedly installed on the mounting frame 361, and are arranged on the rear side of several first pusher inclined plates 362 and several second pusher inclined plates 363 along the seed potato conveying direction.

[0083] During operation, when the seed potato moves to the vicinity of the cutting gap 35 under the push of the spiral blades, if it fails to fall into the gap in time due to stacking or poor posture, the first pushing inclined plate 362 and the second pushing inclined plate 363 located above the blades will use their inclined setting along the conveying direction towards the cutting gap 35 to apply a lateral guiding force to the seed potato, correct its direction and push it into the cutting gap 35. At the same time, the partition soft bristles 364 installed on the rear side of the inclined plate form a flexible isolation zone to prevent the seed potato from rolling over from above the blades to the non-working area or interfering with each other. This design reduces the probability of congestion of seed potatoes at the cutting entrance, ensures the continuity and accuracy of feeding, and improves the smoothness of the cutting operation.

[0084] The alignment device 3 also includes a receiving device 37, which includes:

[0085] The motor 371 is fixedly connected to the frame 1;

[0086] Both wheels 372 are rotatably connected to the frame 1;

[0087] The conveyor belt 373 is drivenly connected to two rollers 372 and is located below a plurality of first helical blades 33 and a plurality of second helical blades 34.

[0088] During operation, the motor 371 drives the rotating wheel 372 to rotate, which in turn drives the conveyor belt 373 to circulate below several first spiral blades 33 and second spiral blades 34. Smaller seed potatoes that do not require cutting fall directly from the cutting gap 35 during the arranging process and land on the conveyor belt 373, where they are then smoothly transported to the next process. This design achieves automatic screening and separation of small seed potatoes, preventing them from entering the cutting device 4 and causing waste or equipment jamming. At the same time, it ensures the continuous operation of the arranging device 3 and improves the automated grading processing capability.

[0089] The cutting device 4 includes:

[0090] The cutting motor 41 is fixedly connected to the frame 1;

[0091] The cutting shaft 42 is rotatably connected to the frame 1;

[0092] Several circular cutters 43 are fixedly connected to the cutting shaft 42, and each of them corresponds to several cutting gaps 35.

[0093] During operation, the cutting motor 41 drives the cutting shaft 42 to rotate, which in turn drives several circular cutters 43 on the shaft to rotate synchronously. These circular cutters 43 correspond one-to-one with each cutting gap 35 in the aligning device 3. When the seed potato is pushed into the cutting gap 35 by the spiral blades, the rotating circular cutter 43 cuts into the gap precisely, cutting the seed potato accurately. This achieves the linkage between the cutters and the aligning device 3, thereby completing the seed potato slicing operation efficiently and neatly.

[0094] The coating device 6 includes a coating assembly 61, which includes:

[0095] The receiving hopper 611 is fixedly connected to the frame 1 and is used to receive the seed potatoes after they have been cut into pieces.

[0096] The coating motor 612 is fixedly connected to the frame 1;

[0097] Several drive wheels 613 are rotatably connected to the frame 1, and all of them are connected to the output end of the coating motor 612.

[0098] Several support wheels 614 are rotatably connected to the frame 1;

[0099] The coating roller 615 has a bottom side connected to a number of drive wheels 613 and a bottom side connected to a number of support wheels 614.

[0100] Several stirring paddles 616 are fixedly connected to the middle of the inner wall of the coating roller 615;

[0101] Several reverse discharge devices 617 are fixedly connected to the conical surface of the discharge end of the coating roller 615.

[0102] During operation, the diced seed potatoes fall into the receiving hopper 611 through the feeding channel 5. The coating motor 612 starts, driving several drive wheels 613 to rotate. The friction force drives the coating roller 615 to rotate on the support wheel 614. When the roller rotates forward, several stirring paddles 616 in the middle of the inner wall rotate with the cylinder, fully spreading and mixing the seed potatoes and wood ash. The water absorption properties of the wood ash quickly absorb the moisture from the cut surfaces and form a protective coating layer. At the same time, the reverse discharge device 617 fixed on the conical surface of the discharge end generates a reverse thrust to prevent the seed potatoes from accumulating at the cone opening. When coating is complete and discharge is required, the coating roller 615 rotates in the reverse direction. At this time, the stirring paddles 616 and the reverse discharge device 617 work together to smoothly push the coated seed potatoes out of the cylinder. This design achieves the dual functions of mixing and coating and automatic discharge through forward and reverse rotation control, eliminating the need for an additional discharge mechanism. This simplifies the structure and ensures the continuity of the coating process and the thoroughness of the discharge.

[0103] The coating device 6 also includes a spraying assembly 62, which includes:

[0104] The receiving hopper 621 is fixedly connected to the receiving hopper 611 and is used to receive wood ash.

[0105] The conveying pipe 622 is fixedly connected to the receiving hopper 611 and is connected to the receiving hopper 621;

[0106] The nozzle 623 is fixedly connected to and communicates with the conveying pipe 622, and is located inside the coating roller 615;

[0107] An air pump 624 is fixedly connected to the receiving hopper 611 and is connected to the nozzle 623 through an air pipe.

[0108] During operation, wood ash is fed into the receiving hopper 621 and falls along the conveying pipe 622. The air pump 624 is activated, delivering high-pressure airflow to the nozzle 623 through the air pipe. The negative pressure generated at the nozzle 623 draws in the wood ash from the pipe and disperses it, spraying it evenly as a mist onto the surface of the seed potatoes tumbling inside the coating roller 615. This design achieves quantitative and uniform application of wood ash, avoiding uneven distribution or waste caused by manual ash spreading. It ensures that each cut seed potato is fully coated with wood ash, effectively absorbing moisture from the cut, promoting healing, and forming a consistent protective layer.

[0109] Working principle: During operation, seed potatoes are first stably conveyed to the alignment device 3 by the feeding device 2. Under the synchronous rotation of all drive shafts 32 driven by the drive assembly 31, the first spiral blade 33 and the second spiral blade 34 fixed on it rotate accordingly. The bidirectional pushing section in the middle, due to the opposite rotation of the blades, generates a forced flipping and tearing effect on the piled seed potatoes to break the congestion and push them to the cutting gap 35 between the adjacent bidirectional pushing sections. Seed potatoes located at the edge enter the unidirectional pushing section and are directionally pushed to the cutting gap 35 between the unidirectional pushing section and the bidirectional pushing section under the unidirectional pushing force. During this process, the pushing surface on the blades generates an axial pushing force on the seed potatoes. When the seed potatoes reach the edge of the cutting gap 35, the guide surface at the tip of the blades guides them to slide into the cutting gap 35. At the same time, the pushing inclined plate above applies a lateral guiding force to the piled or poorly positioned seed potatoes to correct their direction and push them into the gap. The soft bristles 364 on the rear side prevent the seed potatoes from rolling and interfering. Smaller seed potatoes fall directly from the cutting gap 35 during the sorting process and are automatically sorted and transported to the next process by the receiving device 37 below. Normal-sized seed potatoes are precisely cut by the rotating circular cutter 43 in the cutting device 4, which corresponds to the cutting gap 35. After being cut, the seed potatoes fall into the receiving hopper 611 of the coating device 6 through the feeding channel 5, and then enter the coating drum 615. When the drum rotates forward, the stirring paddle 616 on the inner wall mixes it with the wood ash that is evenly sprayed by the spraying component 62. The wood ash absorbs water and quickly dries the cut surface to form a protective layer. When the coating is completed and the drum reverses, the stirring paddle 616 and the reverse discharge device 617 at the discharge end work together to smoothly push the coated seed potatoes out, thus completing the integrated operation from seed potato sorting and cutting to coating and disease prevention.
